According to the National Institutes of Health (NIH), the recommended daily intake of calcium for individuals between the ages of 14 and 18 years old is 1300 mg/day. Therefore, Michael requires 1300 mg of calcium every day. The answer is b. 1300 mg.
Calcium is an essential mineral required for many physiological processes in the body, including building and maintaining strong bones and teeth, nerve transmission, muscle function, and blood clotting. Adequate calcium intake is particularly important during childhood and adolescence when bone growth and development are most rapid.
The recommended daily intake (RDI) of calcium varies depending on age and gender. For example, the RDI for calcium for a 17-year-old male is 1300 mg per day, while for a female of the same age, it is 1200 mg per day. However, certain factors can increase the need for calcium, such as pregnancy, lactation, and certain medical conditions.
Calcium can be obtained from a variety of food sources, including dairy products, leafy green vegetables, tofu, and fortified foods and beverages. Calcium supplements can also be taken if dietary intake is insufficient. It's important to note that excessive calcium intake can have negative health consequences, including kidney stones, so it's essential to speak with a healthcare professional before starting any calcium supplements.

What layer of the Earth does the upper surface of the cross-section represent? Group of answer choices Inner Core Outer Core Mantle Crust
Answer:
Hello! Your answer is...
The lithosphere is the rocky outer part of the Earth. It is made up of the brittle crust and the top part of the upper mantle. The lithosphere is the coolest and most rigid part of the Earth. The crust is the layer that you live in. The Outer and Inner Cores are hotter. The temperatures of the crust vary from air temperature on top to about 1600. The asthenosphere is the part of the mantle that flows and moves the plates of the Earth.
Explanation:
Hope this helps you! I'm new, but am really smart and nice. Hope you enjoy your time on brainly!
The crust of the Earth, the uppermost layer visible in a cross-section of the planet, is halfway through at this point. The crust, which only accounts for around 1% of the Earth's total volume, is made up of igneous, metamorphic, and sedimentary rocks.
What is the upper surface of the cross-section of Earth?The rocky exterior of the Earth is known as the lithosphere. It is composed of the uppermost layer of the upper mantle and the brittle crust. You live in the crust of the earth. It is hotter in the outer and inner cores.
The crust varies in temperature from the top air temperature to roughly 1600. The Earth's tectonic plates are moved by the asthenosphere, a region of the mantle.
Therefore, Mantle Crust layer of the Earth does the upper surface of the cross-section represent.

What form of energy is responsible for producing changes that occur in Earth’s hydrosphere?
Answer:
the sun because energy from the Sun heats the Earth unevenly. As a result, convection currents develop in the atmosphere and ocean. These redistribute heat in the atmosphere and oceans.
Answer: Hydropower is created when rapidly flowing water turns turbines inside a dam, generating electricity. Nuclear energy is produced at power plants by the process of nuclear fission. The energy created during nuclear reactions is harnessed to produce electricity.

Answer:
You can separate them according to the shapes of their beaks.
Some have longer, pointier beaks whilst others have flat and short beaks.
This is because they eat different things: seeds vs worms and insects.
This means that the shape of their beak is an adaptation (it enables their survival) because it makes it easier for them to consume food.
This is known as occupying different niches in the habitat, because even if they all live in one area, they will eat different things, meaning that they will always have enough food to survive.

A new species can form when a group of individuals remains completely separated from the rest of its family long enough to evolve different traits that prevent reproduction. true or false
Answer:
True
Explanation:
It is true that a new species can form when a group of individuals remains completely separated from the rest of its family long enough to evolve different traits that prevent reproduction.
This happens due to physical separation of members of a population.
Geographic isolation :Geographic isolation occurs when populations are separated by geographical barriers like rivers, mountain etc.The population is separated from exchanging genetic material within the same species and results in evolution of a different trait.

Suppose that the same island experiences environmental
conditions that prevent the growth of large seeds. What do you think would happen to
the average size of finch beaks? Explain your reasoning.
Answer:
The size of finch's beak depends on the size of seeds.
Explanation:
The average size of finch beaks also changes because the size of finch beak changes according to the size of seed available. If the environment contains large sized seeds so the population of finch having small beak size increases due to food availability while on the other hand, if the region contains large sized seeds so the population of finch having big beak size increases so according to the size of seeds, the size of finch's beak also changes.

What needs to happen FIRST for a fossil to form?
Answer:
for a fossil to form, an organism must be buried quickly so that any oxygen is cut off and its decay slows down or stops. ... Fossil formation begins when an organism or part of an organism falls into soft sediment, such as mud.
Explanation:
For a fossil to be formed, it is required for a plant or an animal to be covered by the sediment. Thus, the correct option is D.
What is the process of fossil formation?Fossils are the preserved evidence of the organisms which were present on this planet once. There are four types of process which contribute to the formation of a fossil. These are mineralization, carbonization, encrustation and distillation. These processes occur once a living organism has become trapped within the surrounding sediment, and it is primarily depend upon the mineral composition of silt and water available.
Fossil formation begins when a living organism or any part of an organism falls into the soft sediment, such as mud. The organism or part of it then gets quickly buried by more sediment. As more and more sediment collects on top of the organism, the layer with the organism or part becomes compacted and it undergoes deep into the Earth.
Therefore, the correct option is D.

If you drink a gallon or more of fresh water at a single sitting, what happens to your blood and then what might happen to the cells in the blood?
Answer:
I hope this will help
Explanation:
When you drink too much water, your kidneys can't get rid of the excess water. The sodium content of your blood becomes diluted. This is called hyponatremia and it can be life-threatening.
Hyponatremia is a low sodium concentration in the blood. It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. Symptoms can be absent, mild or severe. Mild symptoms include a decreased ability to think, headaches, nausea, and poor balance.
